At VFP. Summarize the basic operation commands of the table, describe the basic format of the commands, and illustrate the functions of the commands with examples.
The command to mark the deletion, modification and location of table records (logical deletion mark) format: delete [for lexpressional]1. The command to restore records (which can be recalled after being logically deleted) format: recall [for lexpressional] 2. Marked records are physically deleted (they will not be recovered after repeated deletion). Format: Pack III. Physically delete all records in the table (delete all records in the current table, but the table will not be deleted) Format: Zap IV. Modify the table record format directly with the Replace command: replace [Scope][For][,,,,] For example, add 100 yuan to all women. Use salary+100v. displayrecord command format: list/display [[fields] field list] [for l expression] [off] [to printer [prompt] | to file mame]. Field list is a comma-separated list of field names, lexpression ol is a conditional expression, which is used to specify that the qualified records will be displayed, and To Printer means to send the results to the printer. If Prompt is used, the print setting dialog box will pop up before printing. To File means to send the results to a file, and filemame is the file name. 6. Use Go To(Go) to find the format: Go necordumber | Top | Bottom, where necordumber is the record number and Top is the title. When the index is not used, the record with record number 1 is used before the record with record number 1, and the Bottom is the footer, which has the opposite effect to Top. 7. Use the Skip command to locate the format: Skip [nrecords] where nrecords can be a positive integer or a negative integer (default value: 1), and move backward when it is positive, and vice versa. Eight, use the Locate command to locate the format: Locate For lexpressionl where lexpressionl is the expression of query or location. If there are no records that meet the conditions, the pointer points to the end of the file. If you want the hour hand to point to the next record that meets the positioning conditions, please use the Continue command. In order to judge whether they have Found a qualified record, they can use the found function. If so, the function returns. Otherwise, it is. The structure of F..Locate command: locate for lex pressure al do while found ()//processing,,,, Continue Enddo.
